According to one embodiment, a signal processing apparatus includes a processer. The processor separates a plurality of signals, which are received at different positions and come from different directions, by a separation filter. The processor estimates incoming directions of a plurality of separate signals respectively, and associates the plurality of separate signals with transmission sources of the plurality of signals. The processor associates either one of a first attribute and a second attribute with the separate signals which are associated with the transmission sources of the signals based on results of the estimation of the incoming directions in a first period, and add either one of first label information and second label information.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A signal processing apparatus comprising: a memory; and a hardware processor electrically coupled to the memory and configured to: separate a plurality of signals using a separation filter to obtain a plurality of separate signals, and output the plurality of separate signals, the plurality of signals including signals which come from different directions, estimate incoming directions of the plurality of separate signals, respectively, and associate the plurality of separate signals with the incoming directions, and associate either one of a first attribute or a second attribute with the separate signals from the plurality of separate signals which are associated with the incoming directions based at least in part on results of the estimation of the incoming directions in a first period, respectively, the first period being set by at least one of button operations.
2. The signal processing apparatus of claim 1 , wherein the hardware processor is further configured to associate the first attribute with a signal from the plurality of separate signals whose incoming direction is estimated with a greater than first threshold certainty for at least a first threshold percentage of the first period, and associate the second attribute with the other signals of the plurality of separate signals.
3. The signal processing apparatus of claim 2 , wherein the first period comprises a period in which a first button is operated.
4. The signal processing apparatus of claim 2 , wherein the first period comprises a period until a first time elapses after a first button is operated.
5. The signal processing apparatus of claim 2 , wherein the first period comprises a period from when a first button is operated to when a second button is operated.
6. The signal processing apparatus of claim 2 , wherein the first period comprises a period from when a first operation is performed with respect to the first button to when a second operation is performed with respect to the first button.
7. The signal processing apparatus of claim 1 , wherein the first period comprises a period in which a first button is operated.
8. The signal processing apparatus of claim 1 , wherein the first period comprises a period until a first time elapses after a first button is operated.
9. The signal processing apparatus of claim 1 , wherein the first period comprises a period from when a first button is operated to when a second button is operated.
10. The signal processing apparatus of claim 1 , wherein the first period comprises a period from when a first operation is performed with respect to the first button to when a second operation is performed with respect to the first button.
11. The signal processing apparatus of claim 1 , wherein the hardware processor is further configured to identify the separate signals from the plurality of separate signals as voices, associate the first attribute with a separate signal in which a first signal is identified within the first period, and associate the second attribute with other separate signals from the plurality of separate signals.
12. A signal processing method comprising: separating a plurality of signals using a separation filter to obtain a plurality of separate signals, and outputting the plurality of separate signals, the plurality of signals including signals which come from different directions; estimating incoming directions of the plurality of separate signals, respectively, and associating the plurality of separate signals with the incoming directions; and associating either one of a first attribute or a second attribute with the separate signals from the plurality of separate signals which are associated with the incoming directions based at least in part on results of the estimation of the incoming directions in a first period, respectively, the first period being set by at least one of button operations.
13. An attribute association apparatus comprising: a memory; and a hardware processor electrically coupled to the memory, and configured to: receive a plurality of sounds coming from different directions, and determine a plurality of separate sounds from the plurality of sounds, receive at least one of button operations, and associate either one of a first attribute indicative of a specific speaker or a second attribute indicative of a nonspecific speaker who is different from the specific speaker with each of the plurality of separate sounds based on results of estimation of incoming directions in a first period which is set by the at least one of button operations.
